Comparative analysis with Wernicke's aphasia Erislandy Omar Martínez Mariana Milena Pino Melgarejo Omar Amed Cruz Cardona Víctor Manuel Pardo Maza Medicina Aphasia schizophrenia oral language neuropsychology neurolinguistics Introduction: In schizophrenia, the presence of a digressive oral discourse is very frequent, plenty of paraphasias and neologisms, provoked by the alterations of thought, which is common in thisillness. This form of empty oral discourse, full of paraphasias and neologisms, is one of the characteristic clinical manifestations of Wernicke's aphasia; with the difference that, in thesepatients, the symptomatology is linguistic, not secondary to alterations of thought. What cognitive mechanisms lead to similar verbal behaviors in both groups of patients? Objective: The purpose of this research was to obtain empirical evidence about cognitive mechanisms that underlie the alterations of verbal communication in both types of patients, from the comparative analysis of their execution in neurocognitive and neurolinguistic tests. Method: The study was implemented in a population of 70 patients organized into two groups: 35 aphasics and 35 schizophrenics. Both groups were subjected to the tests of Semantic Matching of Images, Identification of Homonymous Images and Oral Denomination of Images and Comics. Data processing involved descriptive statistics and Student's t-test for comparative analysis between groups. Results: Indicate that there are no significant differences between groups in semantic processing. In the formation of lexical concepts, schizophrenics show worse performance; while aphasics perform worse on neurolinguistic examination tests. Conclusions: Empirical evidence shows that the oral discourse of both groups of patients is markedly digressive and empty, with paraphasias and neologisms, but linguistically different. 2024 artículo científico 1028-9933 https://www.redalyc.org/articulo.oa?id=551777616005 https://www.redalyc.org/journal/5517/551777616005/ https://www.redalyc.org/journal/5517/551777616005/html/ https://www.redalyc.org/journal/5517/551777616005/551777616005.epub https://www.redalyc.org/journal/5517/551777616005/movil https://doi.org/10.5281/zenodo.10198402 es http://www.redalyc.org/revista.oa?id=5517 Revista Información Científica application/pdf Universidad de Ciencias Médicas de Guantánamo Revista Información Científica (Cuba) Vol.103 |
